ELECTRIC CONNECTOR

PROBLEM TO BE SOLVED: To provide an electric connector structured to obtain stable fitting capable of preventing floating during removal or buckling during insertion by maintaining connection stability while attaining downsizing (especially in a width pitch direction) or reduction in height.SOLUTION: In a receptacle contact 44, an elastic part 444 which is curved at least once or more is included between a contact part 441 and a connection part 443, and a ramp 445 that is inclined is formed from the elastic part 444 to the contact part 441. An expansion engaging part 45 which is located closer to the contact part 441 and communicated with the ramp 445 is further formed. In a housing 42, an expansion locking part 43 is formed at a position, corresponding to the expansion engaging part 45, where an insertion hole 421 into which the receptacle contact 44 is inserted. When removing a plug contact 24, floating is prevented by locking the expansion engaging part 45 to the expansion locking part 43, and buckling during re-insertion is prevented.SELECTED DRAWING: Figure 2 【課題】本発明は小型化（特に、短手ピッチ方向）や低背化を図りつつも、接続安定性を維持し、抜去時の浮き上がりや挿入時の座屈を防止できる安定した嵌合を得られる構造の電気コネクタを提供する。【解決手段】本目的はレセプタクルコンタクト４４には接触部４４１と接続部４４３との間に少なくとも１回以上湾曲した弾性部４４４を有し、弾性部４４４から接触部４４１の間には傾斜した傾斜部４４５が形成され、接触部４４１側で、かつ傾斜部４４５と連設する拡張係合部４５がさらに形成され、ハウジング４２にはレセプタクルコンタクト４４が挿入される挿入孔４２１が設けられる拡張係合部４５に対応する位置に拡張係止部４３が形成され、プラグコンタクト２４を抜去する際に拡張係合部４５が拡張係止部４３に係止することにより浮き上がりを防止し、再挿入時における座屈を防止することを特徴とする。【選択図】 図２
